Transportation and relocation
The transportation of the device, in particular via land transportation, must be made with adequate
means and ways to protect the parts from violent impacts, humidity, vibrations, etc.
Lifting
The means used for lifting must be suitable to bear the weight of the equipment.

Unpacking and inspection
The packaging components must be removed and disposed of according to the applicable
regulations of the country where the device is installed.
Upon opening the packaging, check the integrity of the equipment and verify that all the
components are present.
If you notice defects or deterioration, stop the operations and call the carrier, as well as inform
ABB Service immediately.
Please keep the packaging in the event it has to be returned; the use of inadequate packaging will
void the warranty.
Always store the Quick Installation Guide, all the supplied accessories
and the AC connector cover in a safe place.
Do not open the inverter in case of rain, snow or
high humidity (>95%). During the installation, do
not place the inverter with the front cover
05
facing
the ground.
Install the inverter by following this procedure:
• Place the bracket
01
level on the wall and use it as a drilling
template.
• The selection of the appropriate number and distribution of the
anchors is the responsibility of the installer. The choice must
be made according to the type of wall, frame or other type of
support, and should be sized considering a total load of more
than 4 times the weight of the inverter (total 4x20.5=82 kg
total). Depending on the type of anchor chosen, drill the holes
required for the fixing of the bracket (Figure
A
).
• Carefully lift the inverter and hook it onto the bracket by inserting
the two supports in the slots on the inverter (Figure
B
).
• Proceed to anchor the inverter to the bracket by installing the
two (one each side) locking screws (Figure
B1
).
• Install wireless antenna by screwing it into the dedicated
connector located on the bottom part of inverter
11
(Figure
C
).
WARNING! ELECTRIC SHOCK HAZARD! Hazardous voltages may be present inside the
inverter. The access to the internal zones of the inverter must be carried out after a
minimum waiting time of 5 minutes since the inverter was disconnected from the grid
and from the photovoltaic generator.
• The main connections are made on the lower part (outside) of the inverter. To install the accessories and make the
necessary connections, unscrew the 8 screws using a TORX T20 key and open the front cover
05
; while removing
the screws, pay special attention since additional screws are not supplied.
• After making the connections, close the cover by tightening the 8 screws on the front, while respecting the sequence
and tightening torque (2.5 Nm).

Place and position of installation
-
Refer to the technical data for the verification of the environmental conditions to be
met.
-Do not install the inverter where it is exposed to direct sunlight. If necessary, use
protection that minimizes the exposure, especially for ambient temperatures above
40°C/104°F.
-Do not install in small unventilated spaces where the air cannot circulate freely.
-
Always ensure that the airflow around the inverter is not blocked to prevent
overheating.
-
Do not install near flammable substances (minimum distance 3 m/10 ft).
-
Do not install on wooden walls or other flammable substances.
-Do not install inside residential premises or where a prolonged presence of people
or animals is planned, due to the acoustic noise that the inverter produces during
operation. The noise emission value is strongly influenced by the installation
location (e.g. type of surfaces around the inverter, general properties of the room,
etc.) and the quality of electricity supply.
-Install on a solid wall or structure that is suitable to support the weight of the
equipment.
-
Install in an upright position with a maximum inclination as shown in the figure.
-Respect the minimum distances indicated. Choose a location that allows enough
space around the unit to allow easy installation and removal of the equipment from
the mounting surface.
-Where possible, install at eye level for easy viewing the LEDs.
-Install at a height that takes into account the weight of the equipment.
-When installing multiple inverters, position the inverters side by side while
maintaining the minimum distances (measured from the outer edge of the inverter);
if the space available does not allow this provision, position the inverters in a
staggered layout, as indicated in the figure, in order to make sure that the heat
dissipation is not affected by the other inverters.
-All installations at altitudes above 2,000 m/6,500’ must be assessed on a case by case basis with ABB Service to determine the proper derating of the input
parameters.
The final installation of the inverter must not compromise the access to any disconnection devices located outside.
Refer to the warranty conditions to evaluate the possible exclusions related to an improper installation.

Check the correct polarity of the input strings and the absence of earth leakages of the PV generator. When the PV panels are exposed
to sunlight, they provide a continuous voltage (DC) to the inverter. Access to the internal inverter zones must be carried out with the
equipment disconnected from the grid and from the PV generator.
Caution! The inverters referred to in this document are WITHOUT AN ISOLATION TRANSFORMER (transformer-less). This type involves the
use of PV panels of an isolated type (IEC61730 Class A Rating) and the need to maintain the PV generator floating with respect to earth; no
generator pole must be connected to the ground.
If multiple strings are connected to the same input, they must have the same type and number
of panels in series. ABB also recommend they have the same orientation and inclination.
If the input strings are connected with input channell in independent mode, take into account
that channel 1 (IN1) supports 20A while channel 2 (IN2) supports 11.5A.
• Observe the maximum input current with respect to quick-coupling connectors. Refer to “String inverters -
Product manual appendix” document available on the site www.abb.com/solarinverters, to find out the make and
model of the quick-coupling connector used on the inverter. Depending on the model of the connectors installed
on your inverter, it will be necessary to use the same model for the corresponding counterparts (by checking the
manufacturer’s website or via ABB for the compliant counterpart).
The use of non-compliant counterparts with respect to the quick-coupling connectors models
present on the inverter, may cause serious damage to the unit and result in the immediate
loss of warranty
• Connect the DC input, always checking the tightness of the connectors.
• Versions of the inverter which are equipped with two independent input channels (i.e. dual maximum power point tracker, MPPT), can be configured as parallel
(i.e. single MPPT).
Configuring Input Mode to Independent (default configuration)
This configuration is set at the factory and involves the use of the two input channels (MPPT) in
an independent mode. This means that the jumpers (supplied) between the positive and negative
poles of the two DC input channels
12
must not be installed,
and that the independent channel
mode should be set during the commissioning phase, in the dedicated section of the internal
webserver
“SETTINGS > SETUP DC SIDE > INPUT MODE”
.
